e9778d20a4 fate/vvc: disable vvc-conformance-OPI_B_3 and vvc-conformance-VPS_A_3 
Both samples rely on a feature our decoder doesn't currently support.

Should fix fate failures on some systems where not even the one single frame
could be generated.

4ab82d2fb6 avcodec/vlc, bitstream: Fix multi VLC with uint8_t syms on BE 
VLC_MULTI_ELEM contains an uint8_t array that is supposed
to be treated as an array of uint16_t when the used symbols
have a size of two; otherwise it should be treated as just
an array of uint8_t, but it was not always treated that way:

vlc_multi_gen() initialized the first entry of the array
by writing the symbol via AV_WN16; on big endian systems,
the intended value was instead written into the second entry
of the array (where it would likely be overwritten lateron
during initialization).

read_vlc_multi() also treated this case incorrectly: In case
the code is so long that it needs a classical multi-stage lookup,
the symbol has been written to the destination as if via AV_WN16.
On little endian systems, this sets the correct first symbol and
clobbers (zeroes) the next one, but the next one will be overwritten
lateron anyway, so it won't be recognized. But on big-endian systems,
the first symbol will be set to zero and the actually read symbol
will be put into the slot for the next one (where it will be overwritten
lateron).

This commit fixes this; this fixes the magicyuv and utvideo FATE-tests
on big endian arches.

098f5e2634 fate/fits: Fix tests on BE 
The fits decoder decodes to native pixel formats; so
the fitsdec-gbrap16be fate test failed on BE despite
its name because the reference file is LE.
This patch fixes this by forcing a pixel format;
the forced pixel format is BE, causing a change
in the reference file.
The fitsdec-gbrp16be test was not affected, because
its source file (lena-rgb48.png from tne FATE suite)
is actually biendian (as if someone had multiplied
8bit content by 257...).
